setfilecon(3)           SELinux API documentation          setfilecon(3)

NAME

       setfilecon, fsetfilecon, lsetfilecon - set SELinux security
       context of a file

SYNOPSIS

       #include <selinux/selinux.h>

       int setfilecon(const char *path, const char *con);

       int setfilecon_raw(const char *path, const char *con);

       int lsetfilecon(const char *path, const char *con);

       int lsetfilecon_raw(const char *path, const char *con);

       int fsetfilecon(int fd, const char *con);

       int fsetfilecon_raw(int fd, const char *con);

DESCRIPTION

       setfilecon() sets the security context of the file system object.

       lsetfilecon() is identical to setfilecon, except in the case of a
       symbolic link, where the link itself has it's context set, not
       the file that it refers to.

       fsetfilecon() is identical to setfilecon, only the open file
       pointed to by filedes (as returned by open(2)) has it's context
       set in place of path.  Since libselinux 3.4 a file opened via
       O_PATH is supported.

       setfilecon_raw(), lsetfilecon_raw(), and fsetfilecon_raw() behave
       identically to their non-raw counterparts but do not perform
       context translation.

RETURN VALUE

       On success, zero is returned. On failure, -1 is returned and
       errno is set appropriately.

ERRORS

       If there is insufficient space remaining to store the extended
       attribute, errno is set to either ENOSPC, or EDQUOT if quota
       enforcement was the cause.

       If extended attributes are not supported by the filesystem, or
       are disabled, errno is set to ENOTSUP.

       The errors documented for the stat(2) system call are also
       applicable here.
